Looking for videos to create a youtube playlist to entertain a group of science-minded teenagers for about 30 min that are largely visual. Sound is fine but the bulk shouldn't be someone talking to the class like an instructor - visualizations are best - ideally they should look really, really cool. Class is engineering focused, but chemistry, robotics, wobbly bridges, comp-sci, biology, are all welcome. [more inside]

I recently accepted a sales position within a company that sells laboratory equipment. (i.e. centrifuges, GC's, HPLC's, Thermal Cyclers, etc) I have no previous lab or science experience, so learning about a myriad of highly technical products/methods is a quite challenging. My main challenge comes from the fact that I need to engage in conversations with scientists, chemists, biologists on a daily basis. With no previous lab experience, I've been having a hard time talking to them on technical level. [more inside]

We're buying a house (still negotiating, hence the anonymity), and we have learned that the level of lead in the water is slightly above the expected range.

"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective?
